How does blade-flapping help to compensate for dissymmetry of lift in helicopters?
Flapping increases the angle of attack and lift on the retreating blade and decreases the angle of attack and lift on the advancing blade.
Difference between a thermosetting and a thermoplastic resin.
Thermosetting resign does not soften when heated and chars or burns rather than melting
Thermoplastic resigns become soft and pliable when heated and hardened when cooled.
